Cars Being Stolen With Keyless Entry
If car owners throw their keys on the table or at their doors, they may unknowingly be allowing thieves to steal their signal. This relay attack is a sophisticated method criminals use to steal keyless vehicles.
Keyless ignition vehicles emit a low-power radio signal to find a matching fob. If the signal is recorded and recreated, it could be used to unlock the car and start it up.
Relay Attack
Imagine your car in your driveway, and your key fob at home. You may be confident that your car is safe, but sophisticated thieves are planning a heist, without you knowing. Instead of slamming windows and jiggling locks, they are using technology to hack into vehicles using digital cracks in their armor. This method of stealing vehicles with keyless access is called relay theft.
The keyless entry system found in cars is controlled by a signal sent from the car's RF transmitter to the key fob. To prevent unauthorized keyless entry, the RF transmitters in the key fob as well as in the car are programmed to activate only when they're within certain distance from each other. However, thieves can circumvent this limitation employing a technique called the relay-attack.
Two people are required to do this: one person stands close to the car and utilizes a device to capture an electronic version of the signal from the key fob. The other, who is at the home of the owner is using a different device to send the key fob signal back to the car. This trickery fools the car into thinking the key fob is close enough to allow it to unlock and start the engine.
This type of attack used to require expensive equipment. But now, you can pick up a relay transmitter on the inexpensive online market and carry out the heist in just a few minutes. This is why it's so popular with car thieves.
All modern cars with keys are at risk. Certain cars are more vulnerable to this type of attack than others. Researchers have tested 237 of the most popular cars and found that all of them could be taken using this method.
Tesla vehicles are believed to be less vulnerable to this type of theft, however Tesla hasn't yet implemented UWB features that could effectively check distances on the car's signal and stop relay attacks. The company has said that they will implement this in the future but until then they are vulnerable. Installing an anti-theft device that safeguards your keys and your car against such attacks is a proactive approach to ensure your car's security.
CAN Injection Attack
Modern cars can protect themselves from theft by sending encrypted messages to the key in order to verify its authenticity. The system is considered to be secure, but criminals have found ways to circumvent it. They simply impersonate the smart key and send messages to the car, letting it unlock the doors, turn off its engine immobilizer, then let them leave the car. To do that they have access to the smart key's internal communications network.
Today, most cars are equipped with between 20 and 200 electronic control units, or ECUs, that control different aspects of the vehicle's operation. They communicate with each other using the CAN bus. To ensure that power consumption is low, these ECUs enter sleep mode with low power that is activated when they receive a wake up' frame. These frames are usually sent by the ECU that manages the smart key or door. However the messages aren't usually authenticated or encrypted, which means that they can be intercepted by criminals with a cheap and simple device.
To accomplish this, they must look for a spot that allows them to connect directly to the CAN bus wires. They usually are hidden in the headlights or in other locations in the front of the vehicle. To access them, you can pull the bumper and cut holes in the headlamp assemblies. website The thieves employ the device referred to as an CAN injection attack to send fake messages that fool the safety systems of the car to unlock and disable the engine immobilizer.
These devices are for purchase on the Dark Web, and work for all major car makers, including BMW, Cadillac, Chrysler, Fiat, Ford, Honda, Hyundai, Jaguar, Jeep, Lexus, Nissan, Renault, Toyota, Volkswagen, Maserati, and more. The researchers who discovered this CAN Injection attack are recommending that all car makers address the issue in their current models, but the fact is that thieves will continue to take whatever they can get their hands on. We can stop this from happening by installing mechanical security measures such as Discloks in every car we own and parking them in well-lit, visible areas.
Blocking the Signal
In a different variation of the relay attack, thieves could use a gadget to jam the signal that is sent by the key fob when the car is locked. The device could be hidden in the pocket or hidden where a burglar is hiding on an open parking lot or even near the driveway being targeted. Owners don't check whether their vehicle is locked after pressing the lock button. Instead, thieves are able to take off with the car since the signal that normally locks the car has been blocked by the crook's device.
They also use devices that amplify signals from the key fob to unlock vehicles. The crooks can do this even when the key is in the driver's pocket, or hanging from an outside hook in the home. Once the car has been locked, hackers can use an ordinary diagnosis port to create the fob with a blank.
To guard against this kind of attack, car manufacturers have developed a variety of anti-theft devices. But, thieves are constantly finding ways to beat these measures.
They've begun using devices that transmit at the same frequency as remote keyfobs to intercept signals. The crooks can then copy the key fob's unlock code and then start the car with this fake signal.
This method is especially popular in the US where a lot of cars are equipped with wireless technology. Owners can start and unlock their car using a mobile application on their smartphone. This technology is likely to be more commonplace as more manufacturers try to link their cars with their owners smartphones.
It is crucial that drivers follow the right procedures to park their vehicles. They should not leave the keys in ignition and should always lock the car when not in it. If they can it is also recommended to use a steering or gearstick locking device. They should also consider having a tracking device fitted to their car in case it's stolen.
Flat Battery
This type of attack is more frequent than people think. The thieves employ low-cost devices that increase the signal from your key fob to enable it to unlock and start your car even if it is off. They then drive the car around a corner or onto a trailer to take off with it. Installing an interruption switch to the starter circuit would protect your car against this. Simpler versions include an ON/OFF button that interrupts the circuit. It costs around $15 and is easy to install.
Car thieves are constantly seeking new ways to rob vehicles. The police as well as the car makers and insurance companies are constantly trying to keep up to their tactics and provide better anti-theft systems for modern vehicles. However, that doesn't stop thieves who are able to adapt quickly and find ways to get around the most up-to-date anti-theft systems.
For example, many thieves use devices that operate on the same frequency as the fob to jam the signal. They place the device in their pocket or somewhere near their vehicle, and it stops the fob's lock command from reaching the car, leaving the vehicle unlocked. This can be accomplished in a matter of seconds. The device is affordable and available on the internet.
Hacking the computer system of the car is an alternative option. This is more difficult but possible. Hackers have developed devices that plug into the diagnostic port of all cars and allow them to connect to the software. From there, they are able to program the blank key fob to start working. This can also be done on older cars, although it is more difficult to do so without removal of the ignition lock.
As more vehicles are linked to drivers' phones the method is likely to be more popular. Once a burglar has the username and password to a vehicle app they can open or start the vehicle by using the app. Fortunately, you can defend yourself from these kinds of attacks by not leaving valuables in your car and parking it in a garage or secured parking lot.
